CORN-SHOCK COMPRESSOR.

SPECIFICATION forming part of Letters Patent No. 735,159, dated August4, 1903.

Application filed November 3, 1902. Serial No. 129,809. (No model.)

To aZZ whom it may concern.-

Be it known that LFREDERIOK H. SCHWARK, a citizen of the United Statesof America, residing at Bonfield, in the county of Kankakee and State ofIllinois, have invented certain new and useful Improvements inCorn-Shock Compressors, of which the following is a specification.

My invention relates to certain new and useful improvements incorn-shock compressors; and its object is to produce a device of thisclass which shall work more effectively than any device heretofore inuse and which shall be simpler and cheaper to construct and easier tooperate.

To these and certain minor ends my invention consists in certain novelfeatures of construction clearly illustrated in the accompanyingdrawings and described in this specification.

In the aforesaid drawings, Figure 1 is a perspective of my improveddevice in use, the figure showing a shock in dotted lines. Fig. 2 is aperspective of the device at the beginning of the tightening operation.Fig. 3 is a similar view of the device at a later stage in thetightening operation, and Fig. 4 is a central longitudinal section ofthe device.

Referring to the drawings, A is a shaft, of wood or metal, as may bedesired, provided with a point a, adapted to be forced into a shock ofcorn or other grain. This shaft is adapted to support the device uponthe shock. A collar B is provided at the end of the shaft A opposite tosaid point. This collar forms a shoulder 17. A circular plate 0,preferably of wood, surrounds the shaft A and is held against theshoulder b by a collar D. The plate C is provided with two metallicplates 0 atits center to prevent und ue wear of the plate 0 upon thecollars D and B, which are preferably metallic. A handle E projectsthrough a suitable perforation in the shaft A and is adapted to rotatethe same. A cord F passes through a suitable perforation a in the shaftA and is held in place by a knot f. The cord F is of suflicient lengthto easily pass around a large shock, leaving a long loose end.

The operation of the device is substantially as follows: The point a ofthe shaft A is driven into the corn-shock at the height at which it isdesired to compress said shock. The cord or rope F is passed around theshock, as shown in Fig. 1, and the end is doubled to form a loop f,which is carried over the shaft A and under that portion of the rope Fextending from the knot around the corn-shock, as shown in Fig. 2.Holding this loop F loosely under the strand of rope, the handle E isturned, thereby rotating the shaft and bringing the loop f between themain strand of the rope and the shaft A, as shown in Fig. 3. Thissecures thel-oose end of the rope to the shaft, and the handle may bethen continuously turned around, winding up the rope from both ends uponthe shaft and compressing the corn-shock. The friction between the twostrands of the rope F and the rim of the plate 0 is such that there isno tendency for the handle to be reversed by the pull of the rope uponit. To secure this result, the plate 0 is made of large diameter, andits edge is made broadly convex, so that a large surface is pressed uponby the rope. I therefore am able to dispense entirely with any othermeans for locking the device to prevent the shock from spreading aftercompression. A further advantage of this type of device lies in the factthat the rope is equally pulled in at both ends instead of from onlyone. This produces a much easier pull, and a device utilizing its forcein this way is much easier to operate than a device by which only oneend of the rope is pulled at once.

I realize that considerable variations can be made in the details ofthis construction, and I do not, therefore, desire to limit myself tothe specific form herein set forth.

I claim as new and desire to secure by Letters Patent- The combinationwith a shaft and a point thereon, of a handle secured to the shaft, atightening-cord also secured to the shaft, a circular plate rotatable onsaid shaft and adapted to have frictional contact with said cord when inplace upon the corn-shock, said plate being so shaped as to have a largesurface in contact with the cord, whereby the friction alone preventsretrograde rotation of the shaft, substantially as described.

In witness whereof I have signed the above application for LettersPatentat Bonfield, in the county of Kankakee and State of Illinois, this29th day of October, A. D. 1902.
